DRAWER AND wfinnnozen Loox.

Application filed March 27, 1923. Serial No. 628,093.

To all whom t may concern:

Be it known that I, GEORGE DoRN, a citizen oit' the United States, residing at Newport News, in the county of Warwick and State of Virginia, have invented a certain new and useful Improvement in Drawer and IVardrobe Locks, of which the following is a specification.

My invention is a new and improved vdrawer and wardrobe lock and the invention primarily has for its object to provide a lock for the purpose stated, of a simple and effective construction which can, be easily and cheaply manufactured, will readily serve its intended purpose and of such construction that it may be quickly placed in position on the drawer or door without the use of fastening screws and Without the necessity of chiseling and cutting the part to which the lock is fitted.

In its more speciic nature the invention comprises a cylindrical or barrel type of lock which can be iitted into a bored recess or hole and which is provided with a cylindrical plunger that will operate in a cylindrical bore or hole, thus making it possible to apply the lock by simply boring two holes in the drawer or door as the case may be.

In its still more detailed nature the invention comprises a lock of the type stated consisting of a base shell and partition plate between which the plunger operates, the base shell being received in and secured to an outer casing or shell between the front wall of which and the opposite wall of the partition plate the sliding lock plates or tumblers are located.

Another object of my invention is to provide means whereby the lock may be used either as a right hand or lett hand lock or as a drawer lock by simply shifting the plunger and the locking plates a one quarter revolution.

Referring now to the accompanying drawings, in whichf Figure 1 is a detail front elevation showing the invention applied to a drawer.

Figure 2 is a vertical section of the drawer showing the lock in elevation.

Figures 3 and 4 are elevations of the lock used as leftand right hand locks respectively.

Figure `5 is a detail perspective view of the base shell with the plunger in place.

Figure 6 isa horizontal section on the lipe 6-6 of Figure 12, the key being in p ace.

Figure 7 is a'detail perspective view `of i the lock andthe key for-operating the saine. Figure 8 is a detailperspective view of the plunger looking at yit from the front.

Figure 9 is a detail perspectiveview of a portion of the plunger looking at it from the rear.

Figure 10 is a vertical central longitudinal section of the lock, the key being yin place and theplunger elevated.

Figure 11 is a view similar to Figure 10, the plunger being locked and in this view shown in elevation.

Figure 12 is a View similar to Figure 11,

the plunger being in the intermediate position. and the keeper being detached.

Figure 13 is a section showing the posi tion of the parts when the lock hasbeen turned to project the plunger tothe locking position.

Figure 14 is a similar View in the unlocked position.

Figure 15 is a similar yview 'with the plunger in the mid position andthe keeper removed (Figures 13, 14and 15 being respectively views corresponding in position to the positions shown inV Figures '10, 11 and 12).

Figures 16 to 19 inclusive are elevations of the several locking plates.

Figure 20 is an elevation of the partition plate.

In the drawings in which like numerals ci reference indicate like parte in all the figures, 1 designates'the drawerv or door, as the case may be, to which the lock is to be fitted. In fitting the lock twoholes are bored, one hole'Q to receive the body of the lock and the other, 3 for theplunger towork in, the hole 3 being drilled to intersect the hole 2 through its axis and being drilled deep enough to leave a recess -for the bottom end'of the plunger when the plunger is retracted, i. e. the, lock unlocked.

4 designates the 'base shell which includes a back and a ange 5, the latter having fourk slots f6 arranged ninety degrees,y apart f and being also provided with threaded holes 7 adjacent the several slots to allow for adjusting the lock to serve asa right or lett handr lock, or as a drawer lock in ay manner hereinafter more clearly explained.

to enter to move the plunger'l up and down.

' The plu-nger is also provided with a lock finger 14 that projects through the several locking slots- 27 of the locking plates 21 to 24 inclusive. 'The A4locking plates have central openings, the 'key engaging portions 26 of which arey definitely cut to cooperate with the several steps 38 'to 41 inclusive of the key 37 whereby when the proper key is applied the several locking plates will be moved in unison to locate the locking finger 14 outl of the locking recesses 28 of the slots 27 and thereby permit the key to turn to raise or lower the plunger' as desired.

17 is the partition plate which divides the lock into two chambers. The plate 17 is adapted to fit within the outer casing or she-ll 30'and lie againsttheJ front edge of the base shell flange,"s ee Figures 6 and 10 to 12 inclusive. The' partition plate 17 has a boss 18 to engage with the front surface 11 of the plunger land itis also slotted at 20 to permit the plunger vto move up and down. The plate l17 also carries a set of guide `fingers 19 to operate in the several slots 25 of the locking plate 21 and to hold the locking plates in proper cooperative relation tov one another and the plate 17, the slot 2O serving to hold the plate 17 in iproper cooperative relation to the plunger 9 since the s'lotted'end of the boss 12 of the plunger projects into the slot 20 of the plate. V

Each plate 21 to 24 yinclusive has corresponding guide 4slots' 25 andcarries leaf springs 29 which serve normally t0 hold the plate over to one side of the casing and maintain the several slots 27 in register and continuously tend to'hold the finger 14 in the lockingrecesses 28.

The outer casing or shell'BO has holes 34 corresponding in location to the slots 6, and holes '35 corresponding in location to the holes the .holes 35 allowingthe use of the screws 36 to secure the base shell 4 and outer casing 30 together. The face 31 of the outer casing #or shell is recessed so as to` provide a curved rim 32 for ornamental'purposes; and thefface 31 is provided with a keyhole slot 33 as indicated.

The partition plate 17 may be `provided with fa stud 43 when a hollow shank key is' to be used to guide and hold the -ke'y to turn on a definite axis.

Iff-the lock is to be used as a drawer lock 'the head 154s screwed into Jthe plunger while the plunger is located as shown in the several figures of the drawings (excepting Figures 3 and 4). lf the lock is 'te be used as a wardrobe lock, right or left hand lock, the screws 36 are withdrawn from engagement with the base shell holes 7 and the shell 30 given one-quarter turn right or left with respect to the base shell 4, it being understood that wheny this is being done the hey Shall have been inserted and the plunger 9 projected to the position indicated in Figure 12 so as to clearv the casing 30. After the casing has been given the'one-quarter turn the screws 36 are/replaced. If the lock is to be used in a position where the plunger head must work downwardly to effect the locking act instead ofupwardly as in Figure 1, the plunger head 15 is unscrewed from the top ofthe plunger and screwed into the bottom of the plunger. This would be the case were the lock used on the fixed partof a bureau and the plunger head made to engage a recess in the drawer edge.

While two pairs of slots 6 are shown on the base member 4 one pair alone may be i:-

used the two airs beino` arovided for cona p b venience in assembling the parts.

lt should further be understood that in changing the outer casing to locate the key hole slot from the position shown in Figure 1:.

1 to either the position shown in Figure 3 or that shown in Figure 4, the base 4, the plunger 9 and the disks shown in Figures 16 to 20 Yinclusive remain in their respective positions while the shell 30 is being turned, the object of turning the shell 30 being to locate the key hole slot always in the proper up and down position regardless of whether the plunger' and its head are movable in avertical or a horizontal direction.v

rlhe key 37 has steps 38 to 41 inclusive equal in number to the number of locking plates employed, this number being variable to suit the idea of the lockmaker or de'- signer. rlhe key also has an additional step 42 to cooperate with the plunger slot 13.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of the invention will be clear to thoseskilled in the art.
